|Condition or disease||Intervention/treatment||Phase|
|Dry Age Related Macular Degeneration||Biological: MA09-hRPE||Phase 1 Phase 2|
This study is a Phase I/II, open-label, non randomized, sequential, multi-center clinical trial. There will be 5 cohorts, the 4 low vision cohorts will contain 3 patients, the better vision cohort will contain 4 patients. The enrolled cohorts will be as follows:
Three AMD patients- 50,000 MA09-hRPE cells transplanted Three AMD patients- 100,000 MA09-hRPE cells transplanted Four Better Vision AMD patients- 100,000 MA09-hRPE cells transplanted Three AMD patients- 150,000 MA09-hRPE cells transplanted Three AMD patients- 200,000 MA09-hRPE cells transplanted
Patients will be enrolled sequentially, and within each cohort of 3 patients, each patient's clinical course over the first 6 weeks following cell transplantation will be reviewed by an independent (DSMB) before enrollment is opened for the next 2 patients. A full safety assessment of all 3 patients in each cohort will be made by the DSMB when the 3rd patient in each cohort completes 4 weeks of follow-up, and before the first patient in the next cohort receives a cell transplant. The exception is the better vision group where all patients may be enrolled once DSMB approval has been received.
Each cohort will be enrolled sequentially in turn, with the exception of the better vision cohort which may be enrolled in parallel with the other cohorts.
The day of the cell implantation will be Day 0, and patients will remain in the study until the last visit at 12 months.

Experimental: Subretinal injection of MA09-hRPE
Cohort 1 50,000 cells Cohort 2 100,000 cells Cohort 2a Better Vision 100,000 cells Cohort 3 150,000 cells Cohort 4 200,000 cells
- Safety of hESC derived RPE cells [ Time Frame: 12 Months ]
The transplantation of hESC-derived RPE cells MA09-hRPE will be considered safe and tolerated in the absence of:
- Any grade 2 (NCI grading system) or greater adverse event related to the cell product
- Any evidence that the cells are contaminated with an infectious agent
- Any evidence that the cells show tumorigenic potential
- exploratory evaluations for potential efficacy endpoints. [ Time Frame: 12 months ]
Secondary endpoints will be evaluated as exploratory evaluations for potential efficacy endpoints.
- Change in the mean of BCVA
- Autofluorescence photography
- Reading speed
Evidence of successful engraftment will consist of:
- Structural evidence (OCT imaging, fluorescein angiography, slit-lamp examination with fundus photography) that cells have been implanted in the correct location
- Electroretinographic evidence (mfERG) showing enhanced activity in the implant location
